TEMPORARY BINDER.

SPECIFICATION forming part of Letters Patent No. 644,391, dated February27, 1900. Application filed March 28, 1896. Serial No. 585,176, (Nomodel.)

To all whom, it may concern:

Be it known that I, JAMES E. WOODWORTH, a citizen of the United States,and a resident of Milwaukee, in the county of Milwaukee and State ofWisconsin, have invented cer tain new and useful Improvements inTemporary Binders; and I do hereby declare that the following is a full,clear, and exact description thereof.

Io My invention has for its object to simplify and cheapen that class oftemporary binders in which suit-able strips or cover-sections are adjustably `unitedl A further object of the invention is to facilitate theadjustment of the strips or coversections; and said invention consistsin certain peculiarities of construction and combinations of partshereinafter set forth,with reference to the accompanying drawings, and

zo subsequently claimed.

In the drawings, Figure l represents a sectional view of a portion of atemporary binder embodying my improvements, the section being indicatedby the line l l in the succeeding figure; Figs. 2 and 3, planl viewsillustrating two positions of a lever-controlled stem embodied in myimprovements; Figs. 4 and 5, horizontal sections viewed on line i 5 inthe first figure and which also illustrate 3o two positions of thelever-controlled stem; Fig. 6, a section on the plane indicated by line6 6 in the third figure; Fig. 7, a sectional view on the plane indicatedby line 7 7 in the suceeding ligure, showing my improvements inconnection with another form of binder from what is shown in precedingfigures; and Fig. S, a plan view of a portion of this latter form ofbinder,partly broken away.

Referring by letter to the drawings, A B

4o represent strips made from metal or other suitable material, and eachof them may be of approximately right-angle contour, the rear of oneoverlapping the rear of the other to obtain a stiff back for the binder.As herein shown, the cover-sections O D may have iiexible joints l) cwiththe aforesaid strips.

That form of binder embodying the approximately right-angle strips isbest illus- 'trated in Fig. 1; but, as shown in Figs. 7 and 8, saidstrips may be unbent plates joined to a flexible back, said strips inthe latter showing being faced with wood, strawboard, or other suitablematerial.

Both forms of the binder herein shown are organized with especialreference to apertured stubs E in fleXiblejoint connection with leaves Eon which to mount photographs or samples of various kinds.

In that form of binder best illustrated by Fig. l the strip A isgenerally provided with 6o a plurality of cylindrical posts F, and inaccordance with the present invention each of the posts is provided uponits interior with alternate ridges and depressions to form at least onecorrugated surface d longitudinally of said post, but lnon-continuousaround the interior of the same. The alternate ridges and depressions ofeach corrugated surface may be straight or inclined, as found mostconvenient in practice, those herein shown 7o being inclined as a resultof screw-threading the interior of a post and then cutting away thethread at one or more intervals of the circle longitudinally of thepost. As a matter of fact in the present showing there are twodiametrically opposite corrugated surfaces CZ and twodiametrically-opposite channels c in the post, the channels beingintermediate of said surfaces. Each post is for l the engagement of astem G, having as many 8o corrugated surfaces f longitudinally thereofas there may be like surface or surfaces CZ within said post. Thegeneral contour of the stem is such that registration of its corrugatedsurface or surfaces f with the chan- V nel or channels c in the postwill permit telescopic engagement of this post and said stem, the twobeing held in adjusted position one upon the other as a result ofpartial rotation of the aforesaid stem to cause interlocking 9o of theircorrugated surfaces.

The partial rotation of the stemv G may be effected by a lever-arm ll,made fast thereto, and while said stem may be in permanent pivotalconnection with the strip B to extend inward therefrom it is preferableto have said strip independent of the aforesaid stem. To this end stripB is shown provided with an aperture g to permit the passage of acorrespending head I on the stem G, and upon partial rotation of thisstem to lock the same in the post F said head will come in position tooverlap the solid portion of said strip, the latter being herein shownat rest against the inner end of the lever H, fast on the aforesaidstem. lVhen the stem G is flat, as herein shown, it is preferable toshield and conceal the same with a sleeve J, that has telescopic play onthe corresponding post, this sleeve being provided at its outer end witha iiange 7L, that laps one of the apertured leaf-stubs E abovespecified. The sleeve is also employed to fill up space in the aperturedleaf-stubs.

Figs. 7 and S illustrate that the round hollow part F may constitute thestem and the previouslydescribed part G the post, the former beingengaged by the sleeve J in a position reverse to that shown in precedingiigures. Figs. 7 and 8 also illustrate strip B, provided `with adepression t' for the head I of the part having the lever-arm I-I inconnection therewith, the depression and head being concealed by anoverlapping portion of the flexible back K, that is also shown joined toboth strips A B.

The strip B being suitably apertured, it can be readily detached fromthe stem-head I and as readily restored to working position when thelever-arm I-I is turned to bring said head and corresponding strip-apertnre in register.

As herein shown, the lever-arm H extends transversely of the adjacentstrip when it is desirable to remove or position the latter, as plainlyshown in Figs. l, 2, and 7. The lever-arm being thus positioned, theremay be telescopic adjustment or detachment of the post and stem; butthese latter parts being engaged a partial rotation of said lever-arm tobring the same parallel to the strips A B, as shown in Fig. 3, will locksaid post and stem in their engagement, the head I being also brought inposition to lock the upper strip B lin place.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. A temporary binder embodying two parallel strips of suit-ablematerial,combined with a telescopic joint consisting of a hollow sectionhaving a corrugated surface within its bore longitudinally thereof butnon-continuous around the same, and another section having an exteriorcorrugated surface that comes in or out of mesh with the one aforesaidwhen said joint-sections are engaged and one of them partially rotated.

2. A temporary binder embodying two parallel strips of suitablematerial,combined with a telescopic joint consisting of a hollow sectionthe bore of which presents alternate channels and corrugated surfaceslengthwise thereof, and another section having corrugated surfaces thatcome within the channels of the former section to permit engagement ordisengagement of both sections, but which mesh with the aforesaidcorrugated surfaces to maintain the joint; this meshing being attainedby partial rotation of one of said sections.

3. A temporary binder embodying two parallel strips of suitablematerial, combined with a telescopic joint consisting of a hollowsection having a corrugated surface within its bore longitudinallythereof but non-continuous around the same, and another section havingan exterior corrugated surface that comes in and out of mesh with theone aforesaid when both joint-sections are engaged; together with alever-arm connected to one of said joint-sections, the latter beingrotative upon the other.

4. A temporarybinder embodying two parallel strips of suitable material,combined with a telescopic joint consisting of a hollow section having acorrugated surface within its bore longitudinally thereof butnon-continuous around the same, and another section having an exteriorcorrugated surface that comes in or out of mesh with the one aforesaidwhen both j oint-sections are engaged and one of them partially rotated;together with a sleeve that loosely engaging the'outer jointsectionserves as a shield for the inner one.

5. A temporary binder-embodyin g two parallel strips of suitablematerial one of which is apertured, combined with a telescopic jointconsisting of a hollow section having a corrugated surface within itsbore longitudinally thereof but non-continuous around the same, anothersection having an exterior corrugated surface that comes in and out ofmesh with the one aforesaid when both sections are e11- gaged and one ofthem partially rotated, and a head on the rotative joint-section forpassage through the apertured strip and opposition to its outer face. l

6. A temporary binder embodying two parallel strips of suitable materialone of which is apertured, combined with atelescopic joint consisting ofa hollow section having a corrugated surface within its borelongitudinally thereof but non-continuous around the same, anothersection having an exterior corrugated surface that comes in and out ofmesh with the one aforesaid when both sections are engaged and one ofthem partially rotated, a head on the rotative joint-section for passagethrough the apertured strip to be brought in opposition thereto, and asleeve that loosely engaging the outer joint-section serves as a shieldfor the inner one.

7. A temporary binder embracing two parallel strips of suitable materialone of which is apertured, in combination with a telescopic joint onesection of which has rotative interlocking connection with the other, ahead on the rotative j oint-section for passage through the aperturedstrip to be brought into opposition thereto, a lever-arm connected tothe rotative joint-section,and a sleeve that loosely engaging the outerjoint-section serves as a shield for the inner one.
